Top 8 amazing science facts that will make you revisit your science books
Over the past few centuries many scientific discoveries have been made and the science facts relating to these discoveries have amazed one and all. It is high time that some of these amazing science facts be discussed.
8 DNA in a person’s body can stretch 17 times from Sun to Pluto
One of the amazing science facts relating to human body is that the human body contains 23 DNA molecules and has 37 trillion cells. If the entire DNA structure of these cells is uncoiled it will have a length which is equal to 17 round-trips to Pluto.
7 Photon takes 40,000 years to travel from core of sun to surface
Another of the amazing science facts is that a photon takes around 40,000 years to travel from core of sun to the earth surface. In simple words, light that we receive today has been produced from energy that might have radiated millions of years ago.
6 Great Barrier Reef is largest living structure on Earth
Great Barrier Reef is actually the largest living structure on Earth considering the fact that it is an interlinked system of 3000 reefs and around 900 coral islands. However, warning bells have started ringing as this ecosystem is now fading away owing to climate change.
5 You walk equivalent to five times around the world in your lifetime
Another of the amazing science facts is that an average person takes around 7,500 steps on any given day. If it is considered that the person lives for 80 years, he or she would have taken 216,262,500 steps by that time. This would come to an amazing 110,000 miles in the lifetime.
This will come to same as if the person has walked around the world five times in their lifetime.
4 Helium will show surprising properties if cooled to absolute zero
Helium as a gas has many surprising properties. Consider the fact that Helium is just below its boiling point of -269 degree Celsius, then it can flow through molecule thin cracks.
It can climb up and over the sides of a container and can also be in a motionless position when the container is spun over.
3 If Betelgeuse explodes, the sky will light up continuously for two months
The location of Betelgeuse is roughly 430 light years from Earth. It is a supergiant star and has luminosity 10,000 times that of the Sun. As it is nearing the end of its lifespan, Betelgeuse is likely to explode into a supernova any time. Whenever this happens, be it tomorrow or may be a thousand years later, the sky will light up for two months.
2 A blood cell takes 60 seconds to complete a circuit of the body
Human body has around 5 litres of blood and around 70 ml of blood is pumped with each beat. The amount of blood that a heart can pump multiplied by number of beats in a minute would be 4.9 litre of blood. This essentially means that the heart pumps entire blood volume around the body in a minute.
1 You are not alone in the Universe
The universe is made up of 50,000,000,000 galaxies and there are 100,000,000 stars in the galaxy. The Milky Way also consists of 100,000,000 planets and yet we sometimes think that we are alone in the universe.
